@aras resisting the temptation to not change/refactor/delete some (widely used) code for the 'better' is one of the hardest things in software development :)
Also, looking forward to the ECS and job system in Unity, that will make it so much more attractive for creating simulation-heavy games.
@aras For me, getting Probuilder is the biggest burst of awesomeness I can think of. I've tried and failed to learn blender a handful of time. Meanwhile I did a fairly good looking scene (considering I have no art skills at all) with nothing but unity cubes and free textures and a free asset (screws! ). And I couldn't help thinking so many times.. if I just had some more modeling tools in unity :D
